Gold Mining: How Do We Get Gold Out of the Ground Silver Monthly

This process creates anode sludge which contains gold in quantities sufficient to make its recovery profitable. Onethird of all gold is obtained from such byproducts. Silver and platinum are also recovered from the copper anode sludge in quantities large enough to more than pay for the total refining process.

Recovery of Gold and Silver from Copper Anode Slime

This study has shown that gold and silver can be recovered from a complex anode slime containing copper, selenium, and tellurium, but a carefully planned leaching procedure is required. To extract the gold with thiourea, it is necessary to first remove the copper, selenium, tellurium, and most of the silver from the mixture.
